UNITED STATES JOHN MIDGLEY AND \VILLIAM HALL, OF PIUVTUOKET, RHODEISLAND, ASSIGNORS OF ONE-HALF TO VILLIAM F. SAYLES AND FREDERIO O.SAYLES, BOTH OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 319,959, dated June16,1885.

Application filed February 25, 1884. (No model.)

To all whom it may concern.-

Be it known that we, JOHN MIDGLEY and WILLIAM HALL, subjects of theQueen of Great Britain, residing at Pawtucket, in the county ofProvidence and State of Rhode Island, have jointly invented anew anduseful Improvement in Stop-Motions for Combi ng-Machines; and weplan andan elevation of the stop-motion mechanism on a larger scale. Figs. 5 and6 show, respectively, a plan and an elevation of a portion of thestop-motion having a modified form of lever.

A represents the main annular comb, and B B the small annular combs, ofa combingmachin'e, all of which are revolved in the direction of thearrows by suitable gearing driven from the shaft to in a manner wellknown to persons familiar with such machinery. The sliver b,which is theproduct of the machine, is obtained from these combs in the usual andwell-known manner, and in the machine illustrated is delivered by therolls 0 c to the trumpet D, which trumpet twists the sliver and deliversit to rolls EE, which discharge it from the machine. The roll 0 ismounted on a shaft, 0, and, as shown in Fig. 2, is driven from the shafta by the bevel-gears l and 2, the shaft 3, and the gears 4, 5, 6, 7, and8, the latter gear being attached to the shaft 0. The trumpet D isrevolved by a belt, 9, passing over a pulley, 10, on the shaft a. Therolls E E are driven from the shaft a by suitable gearing or in anypreferred manner.

The stop -motion is intended to operate should the sliverb lack therequisite weight by reason of a proper amount of ma'terial not D. Thistrough is pivoted on the short arm of a lever, f, which is pivoted to abracket, g, secured to one of the standards G of the discharge-rolls E.To the long arm of said lever is attached a chain or cord, H, upon thelower end of which a clutch member, K, is suspended. As shown in Figs. 2and 4, thisv clutch member is mounted on a stud, L, and has aclutch-face, 70, which is intended to cooperate when allowed to do sowith a clutchface, in, on the hub of a fellow clutch member, M, alsomounted on said stud. By means of a belt, N, the fellow clutch member Mis constantly driven by a pulley, n, on the shaft 0, or it may be drivenfrom any other convenient source.

Secured to the periphery of clutch member K is a second chain or cord,1?, which passes under a pulley, p, thence upward over a pulley, p, andis secured to an arm, g, on the shipping-rod Q, which is provided withthe usual fork, a, for engaging the driving-belt A. In all the figuresofthe drawings this belt is shown in full lines on the driving-pulley.

Under normal conditions the sliver b will support the clutch member K,so that its clutch-face k will be out of engagement with the clutch-facem 011 the hub of the fellow clutch member M. When, however, from any ofthe causes above enumerated, the stopmotion should operate the trough Fwill rise, and the clutch member K will descend into engagement with theclutch-face m, as shown by dotted lines in Fig. 4, and will be rotatedby the revolving pulley M. The rotation of the clutch member K will windthe chain P around said clutch member, and thereby draw the shipping'rodQ to the right, as shown by dotted lines, and cause the driving belt tobe shipped to the loose pulley A thereby causing the machine to stop.

When the belt is to be shipped to the driving-pulley to start themachine, it will be necessary, in order that the rod Q, may be moved forsuch purpose, that the clutch member K be raised out of engagement withthe clutch-facem so that the chain P can unwind from the clutch member Kas the said rod is moved. The disengagement of the clutch member K fromthe clutch-face in may be effected bygrasping the chain H. and liftingthe clutch member K by hand. \Ve prefer, however, to have this.

operation performed automatically, and have therefore provided a chainor cord, R, which is secured to the chain or cord 1? below the pulley p,as shown in Figs. 2 and 4, and passes over pulleys r and 1", and issecured to the long arm of the leverf. Normally the chain R is somewhatslack. When, however, the clutch member K descends into engagement withthe clutch-face on, and the chain P is being wound around said clutchmember K to ship the belt, as hereinbefore described, the slack of thechain It will be taken up by the said descent of the clutch member K andthe movement of the chain 1?, and the said chain P, through the chain R,will gradually raise the long arm of the lever f, upon which the clutchmember K is suspended, until the clutch member K becomes disengaged fromthe clutch-face m, which is intended to occur when the belt A passes offthe drivingpnlley. The clutch member K will be reainedby the chains 1?and B in its elevated position until the shipping-rod Q is moved totransfer the belt to the driving-pulley. The clutch member K being thusheld out of engagement with the clutch-face m, the chain 1? can unwindfrom the clutch member K to allow the rod Q to be moved, and the sliverI), having been repaired, the said sliver will support the clutch memberK in said elevated position when the chains P and R no longer performthat office.

Although we prefer to employ the trough F, in order that a long hearingmay be obtained upon the sliver, and to pivot the trough to the lever fso that said bearing may be maintained under slight movements of saidlever, due to immaterial inequalities in the sliver, yet the pivotedtrough may be dispensed with, and the short arm of the lever, in anypreferred form, be brought into contact with the sliver, as for instanceas shown in Figs. 5 and 6.

What we claim, and desire to secure by Letters Patent, is

1. A stop-motion mechanism consisting ofa pivoted lever arranged, asdescribed, to bear against a passing sliver, a clutch member suspendedupon said lever, a revolving fellow clutch member located in verticalalignment therewith, and a chain or its equivalent attached to theperiphery of the first-mentioned clutch member and connected with theshipping-rod of the machine, whereby when the sliver breaks the twoclutch members will be brought into engagement, thechain will be woundaround the periphery of the clutchmember to which it is attached, andthe shipping-rod will be moved to transfer the belt, substantially asset forth.

2. A stop-motion mechanism consisting of a pivoted lever arranged, asdescribed, to bear against a passing sliver, a clutch member suspendedupon said lever, a revolving fellow clutch member located in verticalalignment therewith, a chain or its equivalent attached to the peripheryof the first-mentioned clutch member and connected with the shipping-rodof the machine, anda chain or its equivalent attached to thefirst-mentioned chain and to the said pivoted lever, substantially asdescribed, and for the purposes specified.
